If you plan on keeping the neck pickup, you may want to find out the polarization of the neck pickup. So, when you order a pickup you won’t have any phasing issues. You could flip the wires, but if you’re buying new why not get the proper orientation..
Although DC resistance to not a true factor of output, I can safely say you probably got a vintage wind. Super Distortion and Evolution may get you in the ballpark. DiMarzio lists the voltage of their pickup, and you can compare output with tonality. A high output pickup may overpower your vintage wound single coil. You may want to replace the neck pickup with a higher output pickup. Ymmv.
